Joseph Smith (1805–1844), the founder of the Latter Day Saint movement, taught and practiced polygamy during his ministry, and married multiple women during his lifetime. During his lifetime, Smith and the leading quorums of his church publicly denied he taught or practiced it.
In 1852, leaders of The Church of Jesus Christ of Latter-day Saints (LDS Church) acknowledged that Smith had practiced plural marriage and produced a written revelation of Smith's that authorizes its practice. Smith's son Joseph Smith III, his lawful widow Emma Smith, and most members of the Reorganized Church of Jesus Christ of Latter Day Saints (RLDS Church) attempted for years to refute the evidence of plural marriages. They pointed to the historical record that Joseph Smith publicly opposed the practice of polygamy; the suggestion of the RLDS Church was that the practice of Mormon polygamy began in Utah under the leadership of Brigham Young.
The first publication of a list of women alleged to be Smith's plural wives was in 1887, by Andrew Jenson, an assistant church historian of the LDS Church. It included 27 women besides Emma Smith. Currently, historians disagree as to the number and identity of the plural wives which Smith had. Various scholars and historians, including Fawn M. Brodie, George D. Smith, and Todd Compton, have attempted to identify the women who married Smith. The discrepancy is created by the lack of documents to support some of the alleged marriages. As Compton has stated, for many of these marriages, "absolutely nothing is known of [the] marriage after the ceremony." Apart from his marriage to Emma, Smith's marriages were not solemnized under any civil authority and were therefore solely religious unions.
